It's noticeable. The newspaper pic is a little exaggerated because you have the camera tilted down slightly vs. the wall but I can still get a good feel for the barrel distortion. It's always it's most extreme on the edges of photos.
I spent a lot of time looking at the barrel distortion of my 20-35 zoom because I was calibrating it for barrel distortion. I was using it for pano's and that info helps to get a better seam. It was probably the same as the lens you're showing here. I wouldn't consider your lens bad at all. I'd consider it normal for such a wide lens.

Thanks for posting Trevor,
I just didn't want to down a good lens in a review if it didn't deserve it. For all I know this is as good as a prime lense this wide. Ive never used a lense wider than 28mm.
Sharpness! now thats a different story! this lense never seems to get as sharp as a 50 f1.8 at 1.8!
Again, it seems to equal the 18-70 zoom.
Mark.
